PHP 谷歌日历 API

Question

在项目中设置此功能的初始阶段。我已在 Google 开发者页面启用它并尝试遵循快速入门指南

https://developers.google.com/calendar/quickstart/php

然而，与大多数 Google API 教程一样，这个“快速入门”不起作用。我通过授权页面并获得了在终端中输入的代码，但很长一段时间后我才收到错误

PHP Fatal error:  Uncaught RuntimeException: Unable to read from stream in [site root]/vendor/guzzlehttp/psr7/src/Stream.php

不会创建 token.json 文件，但该目录是可写的。

怀疑谷歌代码是错误的。更改第 16 行的范围可以使其正确运行。$client->setScopes("https://www.googleapis.com/auth/calendar.readonly");完整代码：<?phprequire __DIR__ .
